30 Rhode Island Plants. 



522. Carya porcinaj Nutt. Both varieties of this are found 

 in Rhode Island ; the one with subglobose, the other with 

 obovoid fruit. 



. Carya . I have detected a tree in Smithfield 



bearing long elliptical nuts with thick pericarps ; possibly it 

 may prove to be a variety of C. tomentosa, yet it differs much 

 from the ordinary form of that species.

1060. Quercus ambigua ? Michx. f. sylv. II. p. 120, t. 24. 

 I have collected from trees in North Providence, specimens 

 agreeing very nearly with Michaux's figure of Q,. ambigua ; 

 yet Mr. Carey, whose opinions it is always safe to follow, 

 observes, " that, by the small acorns, it must be a variety of 

 Q,. coccinea, but it approaches to the very variable Q,. tinctoria, 

 respecting which our ideas coincide."
